T aZZ whom it may mm.-

Be it known that I,v JOSEPH MI'J'LLER, a cit- I izen of the United States, residing at Dayton, in thecounty of Middlesexand Stateof New Jersey, have invented certain new and useful Improvements in Automatic Water Regulators, of which the following is a.

specification. I I

This invention relates to automatic water regulators for automatically supplying cooling water to the condenser of a refrigerating machine of the absorption or compression type, of'an air compressonan air cooler, in beer or milk coolers, and in various other kinds of apparatus where the cooling water is to be maintained at a certain desired predetermined temperature. i v p I More particularly, my present improvement is identified with thermostatically con trolled water regulators and has for' its primary object to provide a simple and efficiently operating means automatically influenced by the temperature of the water to open a valve and supply additional cooling.

water to the condenser chamber or otherreceptacle.

In one practical embodiment of the invention, I provide a suitablecasting adapted to be connected to the end of the water supply the water to flow from the supply pipe into the condenser chamber.

It is another object of my invention to provide an automatic water regulator of the above type which is of such construction that it can be readily applied to the ordi nary condenser without necessitating any radical structural changes therein. I

\V ith the above and other objects in view,

the invention consists in the improved water regulator and in the form, construction and relative arrangement of its several parts as will be hereinafter more particularly de scribed, illustrated in the accompanying drawin and subsequently incorporated in the subjoined claims.

1y projecting lug. 18,

' Inthedrawing, the figure represent-ska vertical section throughthe cha mber of the condenser having my improved waterv reguf lator arranged therein. Referring in detail to this drawingfor purposes of illustration, I have shown water receiving tank or chamber 5 having an overflow outlet 6 communicating with the upper end thereof. In this chamber the usual condenser'coil 7 *is arranged. The water supply pipe 8 extending-from a pump or other water pressure source has a threaded end 9extending upwardly'through an openibng lnthe bottom wall of the tank or chamer 5. i

The device forming the subject matter of r the present application includes a casting 10 having a "body portion provided "with a;

threaded opening 11 therethrough to receive,

the threaded pipe extension 9. A suitable seat 12 is formed in the castingat one end of this opening upon which a flap valve 13 is normally engaged, said valve having a flexible part 14 of leather or other material ser cured at one end to the horizontally extending arm 15 of the casting by means'of asuitable bolt 16. A disc '17 is fixed upon the upper side of the flexible element 14 and is formed at one side thereof with anupwar the purpose of. which will presently appear. At the opposite side of thereon. The upper. end of this arm is bifurthe ,bbay er. the casting w th respectto the horizontal arnr 15, an upwardly extending-arm 19 is formed cated and fa' lever 20- is pivotally mounted therein upon the transverse pin or bolt .21. This pivoted end of the lever is formed with a web plate 22 having a stop shoulder 23 to:

engage the arm 19 and limit the rocking or pivotal movement of said lever in one direc-' tion. The plate 22 is provided with a depending bifurcated arm 24: the spaced parts of which are connected by a transverse pin or bolt 25, said pin engaging acurved cam face 26 formed on one edge of the upwardly extending. lugf18 of the-disc 17.

The arm 15 terminates in an upwardly extending slotted guide standard 27 in which the other end of the lever 20 is movably positioned. by a coil spring 28 to the arm 15.

Upon the arm 15, the expansible thermostat discs 29 are suitably mounted and simi lar discs 30 are opposed to the discs 29 and detachably connected to the lower end of a This end of the lever is connected rod 8l which has threaded engagement in the lever 20. A suitable handle 32 is fixed to the upper end of this rod whereby said rod may be conveniently adjusted in the le ver to position the discs 30 with respect to the discs 29 and thus vary the degree of expansion: of the discs which is necessary to scribed, as the water in the condenser chain ber absorbs heat from the pipe coil 7 and increases in temperature, upon reaching apredetermined degree, the discs 29 and 30 will be expanded so that the rod 31 and consequently the lever 2-0, are moved upwardly against the action of the spring 28. In this rocking movement of the lever, the pin 25 coacting with the cam face 26 of the lug l8 raises the flap valve from the opening 11 in the casting so that cool water may pass from the supplypipe 8 into the chamber 5. The heated water overflows from said chamber through the outlet 6 from which it may be returned to the source of supply. As the temperature of the body of water in the chamber gradually decreases owing to the admissionof additional cool water, the thermostat discs gradually contract and the spring 28 returns the lever 20 to its normal position so that the weighted flap valve will fall by gravity upon its seat 7 12 and thus shut off the water supply. It

will be apparent that a device of this con struction will be very positive and reliable in its operation and that the water in the condenser chamber is thus automatically maintained at a desired predetermined temperature It will also be apparent that a material saving in the volume of water used can also be realized by means of my invention. Further, it will be noted that the device is of such construction that it can be manufactured and sold as a unit for application to condensers now employed on vari ous types, of apparatus and does not require any material modification or change in the structure of the condenser itself.

It will be apparent that my improvedwater regulator as above described may also be employed with that type of condenser in which the cooling water passes through the pipe coil which is surrounded by the gases to be condensed. In this case, the thermostatic valve is mounted upon the upper end of the pipe coil extending through the bottom wall of the chamber, and as the temperature of the water in said coil varies, the

valve is opened or closed more or less to regulate the flow of the coohng water through the condenser tube.

lVhile- I have herein shown and described an embodiment of my 'present' invention which I have found to be very satisfactory in practical use, itvvill nevertheless be understood that the essential features of the present improvement might be exemplified. in various other alternative constructions and I, therefore, reserve the privilege of resorting to all such legitimate changes in the form, proportion and relative arrangement of the several parts as may be fairly embodied within the spirit and scope of the invention as claimed.

I claim:

1. In combination with a condenser having a conduit for a cooling medium, a pivotally mounted valve controlling. the flow of the cooling medium and having a lug projecting from the outer edge thereof, a yield ingly held pivoted lever, thermostatically controlled means operatively connected with said lever to pivotally move the same in one direction from its normal" position, and means on said lever coactin-g with the lug onsaid valve to move said valve towards an open position in such movement of the leverto thereby regulate the flow of the cooling medium through said conduit.

2. In combination with a condenser chamher and a water supply pipe connected thereto, a casting mounted within said chamber upon the end of the supply pipe, a'va-lve carried by said casting and normally closing communication between the supply pipe and said chamber, a lever pivotally mounted upon said casting, said valve being provided with a cam part, a member carried by the lever to coac-t'with said cam part, and ther mostatic means operatively influenced when the water in said chamber reaches a prede termined maximum temperature tov actuate the lever and thereby'open the valve to admit cool water fromthe supply pipe to said. chamber.

8. In combination with a condenser cham-- ber and a water supply pipe connected thereto, a casting mounted within said chamber upon the end of the supply pipe, avalve carried by said casting and normally closing communication between the supply pipe and said chamber, a lever pivotally mounted upon said casting, said valve being provided with a cam part, a member carried by the lever to coact with said cam part, thermostatic discs mounted upon said casting, an adjustable member carried by said lever, thermostatic discs connected with said member and opposed to the discs on said casting, and a spring connected to said lever and yieldingly holding the same in a normal position, said thermostatic discs expanding when the water in said chamber reaches a maximum predetermined temperature to thereby move said lever against the action of the spring and open the valve to admit and adjustable thermostatically controlled means operatively influenced when the water in, the chamber reaches a predetermined maximum temperature to move said lever against the action of said spring and thereby-open said vali e to admit cool Water from the supplypipe to said chamber.

In testimony that I claim the foregoing as 'myinvention, I have signed myname hereunder.
